Sampling with replacement is used when it is desirable for each item in the population to have an equal chance of being selected each time, and when it is acceptable for the same item to be selected multiple times in the sample. This method is commonly used in bootstrap resampling and in situations where the population is large and well-mixed.

What the methods being used in conducting a research?
Some common methods used in conducting research include surveys, experiments, interviews, case studies, and observations. These methods allow researchers to collect data, analyze it, and draw conclusions based on the findings. Researchers often choose the method that best aligns with their research questions and objectives.
What is the difference between sampling and random sampling?
Sampling involves selecting a subset of individuals or items from a larger population for study. Random sampling is a specific type of sampling method where each individual or item in the population has an equal chance of being selected. In random sampling, the selection of individuals is done purely by chance, reducing bias in the sample.
What negative effects could occur if you used a quantitative sampling method for a qualitative study and vice versa?
Using a quantitative sampling method in a qualitative study could result in a lack of in-depth understanding of participants' experiences and perspectives. On the other hand, using a qualitative sampling method in a quantitative study could introduce bias and limit the generalizability of the findings.
What is a subset of people who are chosen to represent a larger group of people in a psychological study?
A subset of people chosen to represent a larger group in a psychological study is called a sample. This sample should be carefully selected to be representative of the population to which researchers want to generalize their findings. Techniques such as random sampling or stratified sampling are commonly used to ensure the sample is a true representation of the population.
What is opportunity sampling?
Opportunity sampling is a type of non-probability sampling technique where researchers select participants who are readily available and willing to participate in the study. This method is convenient but can introduce bias because the sample may not be representative of the entire population.
Difference between sampling with replacement and without replacement?

Is sampling with replacement a finite population?
no
When you sample with replacement are the trials independent?
They are, if the sampling and replacement processes don't introduce any bias.
What is sampling without replacement?
The representative part of Population is called Sample.
What type of sampling is used to estimate the percentage of defects?
random sampling
Statement of sampling theorem?
sampling theorem is used to know about sample signal.
When sampling without replacement should you use multiplication rule for independents or dependents events?
hell no nigaa
What does it mean when sampling is done without replacement?
Once an individual is selected, the individual cannot be selected again.
What is the difference between flat top sampling and natural sampling?
in flat top sampling the electronic circuit required for sampling are less complicated as compared to the one used in natural sampling, at demodulation of the sample it is very difficult to maintain the natural waveform of the natural sampling so flat top sampling can easily be demodulated.
How probability sampling is used?
Probability sampling is used to select a sample from a population in such a way that every individual or element in the population has a known and non-zero chance of being selected. This method ensures that the sample is representative of the population, allowing for generalizations and statistical inferences to be made with greater validity and accuracy. Probability sampling techniques include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
Why is random sampling used by pollsters?
They think that if they used the random sampling after people voted because they want to get a better view of who will be the next president.
What is systematic sampling use for?
In practice, systematic sampling is used on account of its simplicity and convenience. It's easy to explain to the people doing the actual work. It can be justified theoretically wherever the population from which units are to be sampled systematically are randomly distributed. It can be used for sampling households, sampling callers on a telephone line, sampling plants along a transect in (say) a field, sampling people passing through customs, and so on.
